1. Since applications vary, each investigator should titrate the reagent to obtain optimal results. 2. Please refer to us for technical protocols. 3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing. 4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

Purification

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

EphA4/Sek is a glycosylated protein tyrosine kinase of 986 amino acids and an apparent 110-130kDa molecular weight (molecular weight depends on glycocylation level of protein). EphA4 belongs to the Eph subfamily of receptor tyrosine kinases and like many others, it has an amino-terminal ligand-binding domain exposed to the extracellar matrix. EphA4 is predominantly expressed during development (this is common in the Eph family) and because of its mRNA localization, it has been proposed that it may play a role during segmentation of the hindbrain and mesoderm. Tyrosine 602 is a major autophosphorylation site of EphA4 and appears to be the docking site for the intracellular tyrosine kinase fyn.
